The JK1217 Junior Warc antenna was designed as a simple dual band Yagi that performs amazingly on 17 m and 12 m and on a smaller boom. This single feed point Yagi performs like a champion giving great gain and F/R while keeping SWR low on both 12 m and 17 m.

This interlaced yagi gives the best performance at par with any 3-element monoband Yagi in its class on 17 m and 4-element monoband Yagi on 12 m.

*** We strongly recommend to analyze and model before mounting any WARC antenna above or below Tribanders or other Yagi antennas with separation of less than 10 ft. ***
